Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of adhesive bonding processing, in particular to a precise quantity control and leakage prevention type spiral extrusion glue supply device. BACKGROUND

[0002] In the field of adhesive bonding processing, the core value of the spiral extrusion type equipment is to realize the quantitative conveying and precise bonding of the adhesive, and the quantity control precision is a key factor to determine the stability of the bonding quality of the product. However, the traditional spiral extrusion type bonding equipment is limited by the technical architecture, and there are three core pain points in actual production, which is difficult to meet the high-precision processing demand.

[0003] Firstly, the uniformity of premixing and stirring and the material utilization rate are difficult to balance. The traditional equipment generally adopts a single-shaft fixed-track stirring mode, and the stirring blade can only rotate in a single direction. The adhesive forms a fixed circulation in the stirring bin, and the different component materials are prone to stratification and sedimentation, which results in poor mixing uniformity and directly leads to significant fluctuations in the subsequent bonding strength. At the same time, the problem of wall residue is prominent, and there is a lack of active cleaning mechanism. After single stirring, a certain amount of adhesive will be attached to the wall, which not only causes waste of raw materials, but also requires regular shutdown for disassembly and cleaning. The residual adhesive will further contaminate the new material after solidification, forming a vicious cycle.

[0004] Secondly, the quantity control precision of adhesive conveying is interfered by multiple factors, and the stability is poor. The quantity control logic of the traditional equipment depends on the single motor speed regulation, and there is no linkage control mechanism for temperature- viscosity-flow. When the environmental temperature fluctuates, the viscosity change of the adhesive will cause significant deviation of the discharge amount. The spiral conveying channel is designed with equal diameter, which cannot form a gradient pressure, and the adhesive is prone to "pulse discharge" at the end of the conveying, which makes the adhesive coating amount of the same batch of products differ greatly, seriously affecting the bonding consistency.

[0005] Thirdly, the dynamic adaptation ability of sealing and discharging is missing. The sealing structure of the traditional equipment is mostly designed with fixed rubber pad, and the sealing force cannot be adjusted. For high-viscosity adhesives, it is easy to cause overflow due to insufficient sealing force, resulting in material loss. For low-viscosity adhesives, the discharge resistance increases sharply due to excessive sealing, and even causes the conveying motor to overload and stop. The state switching relies on manual knob adjustment, which takes a long time for single switching, and cannot adapt to the fast-paced production change demand of the automatic production line.

In the sealing mechanism 5, the outer tooth transmission ring 51 is engaged with the transmission teeth 59 on the linkage transmission block 53. Under the action of the transmission adjusting screw 54 (driven by the torque servo motor 56, and the torque monitoring sensor 55 monitors the torque), the linkage transmission block 53 slides in the sliding groove of the fixed mounting block 52 through the limiting guide sliding block 57.

[0034] According to Figure 1 , Figure 2 and Figure 3 , the self-adaptive cleaning stirring assembly 7, two inner tooth transmission rings 71 are installed inside the tooth disc protection box 22 at the front end, each of which is provided with a driving tooth disc 73 in the center. The outer end of the driving tooth disc 73 is provided with a linkage tooth disc 72 around, and the driving tooth disc 73 and the linkage tooth disc 72, the linkage tooth disc 72 and the inner tooth transmission ring 71 are all engaged with each other. The shafts of the linkage tooth disc 72 and the driving tooth disc 73 are respectively fixedly connected with the stirring support rod 74 and the stirring rod 75, whose front ends extend into the inside of the premixing stirring treatment box 2. The shaft of one of the driving tooth discs 73 connected with the output end of the stirring motor 78 at the rear end of the tooth disc protection box 22, and the rotating tooth disc 79 outside the outer end of the two driving tooth discs 73 is provided with a transmission chain 710.

[0035] When working, the stirring motor 78 drives the connected driving tooth disc 73 to rotate, which drives another driving tooth disc 73 to rotate synchronously through the transmission chain 710. Under the meshing action, the linkage tooth disc 72 rotates in the inner tooth transmission ring 71 with the driving tooth disc 73, and further drives the stirring support rod 74 and the stirring rod 75 to rotate. The plurality of stirring blades 76 on the surface of the stirring support rod 74 and the stirring rod 75 fully stir and mix the rubber material in the premixing stirring treatment box 2.

[0036] According to Figure 1 and Figure 4As shown, the material control actuator 3 has an upper end that extends to the bottom of the premixing and mixing tank 2 and a lower end that extends to the upper end of the rubber extruder body 1. A control quantity resistance adjustment plate 32 is slidably installed in the limiting grooves opened around the upper inner wall of the transition box 31. Its lower end surface is fixedly connected to the telescopic drive rod 33. The other end of the telescopic drive rod 33 is connected to the electric control drive pump 34. A rotary adjustment control rod 35 is provided in the center of the lower end of the transition box 31. One end of the rod is fixedly connected to the flow guide motor 37. Several flow guide and homogenization fan blades 36 are also arranged on its surface.

[0037] During operation, the electrically controlled pump 34 drives the quantity control plate 32 to slide within the limiting groove via the telescopic drive rod 33, thereby adjusting the size of the feed channel of the transition box 31 and controlling the amount of rubber material conveyed. At the same time, the guide motor 37 drives the rotary adjustment control rod 35 to rotate, which in turn drives the guide homogenizing fan blade 36 to rotate, stirring and homogenizing the rubber material passing through the transition box 31, ensuring that the rubber material entering the rubber extruder body 1 has a uniform texture, and providing a good foundation for subsequent spiral extrusion and conveying processes.

[0038] according to Figure 1 , Figure 5 and Figure 6 As shown, the intelligent temperature controller 6 is located on one side of the outer end of the material control actuator 3. Its core related components are the heat-conducting energy storage chamber 61 which is attached to the outer surface of the conveying cylinder 81 inside the rubber extruder body 1, and several electromagnetic induction heating tubes 62 arranged inside the heat-conducting energy storage chamber 61.

[0039] By adjusting the working state of the electromagnetic induction heating tube 62 and utilizing the heat storage and conduction characteristics of the heat-conducting energy storage chamber 61, the temperature of the rubber material in the conveying cylinder 81 and the rubber material conveyed in the material control actuator 3 is regulated. This maintains a suitable temperature for the rubber material during the processing, avoids changes in the rubber material properties due to unsuitable temperature, ensures that the flowability and viscosity of the rubber material meet the requirements of subsequent processing, and provides temperature protection for the stable operation of the entire equipment.

[0040] Furthermore, the conveying cylinder 81 is fixed inside the rubber extruder body 1, and its front end extends into the discharge through hole of the extrusion terminal box 11. The inner diameter of the conveying cylinder 81 gradually decreases along the axis at the front end. A conveying auger 82 is provided in the center of the conveying cylinder 81. One end of the auger passes through the inside of the rubber extruder body 1, extends into the power drive box 12 and is connected to the conveying motor 83. The flow monitoring sensor 84 is fixedly installed on the upper end of the conveying motor 83.

[0041] When working, the conveying motor 83 drives the conveying auger 82 to rotate, and the reduced inner diameter of the front end of the conveying cylinder 81 produces extrusion on the rubber compound entering the conveying cylinder 81, so as to realize the forward conveying of the rubber compound. The flow monitoring sensor 84 monitors the conveying flow of the rubber compound in real time and feeds back information, cooperates with the overall control of the equipment, ensures the controllable conveying amount of the rubber compound, and provides stable rubber compound supply for the subsequent bonding process.

[0042] According to Figure 1 , Figure 7 , Figure 8 and Figure 9 , the anti-overflow and anti-leakage sealing mechanism 5 is installed with an outer tooth transmission ring 51 at the central part of the inner rear end surface of the extrusion terminal box 11. The outer tooth transmission ring 51 is provided with fixed mounting blocks 52 around the periphery, and a sliding slot is formed at the front end of the outer tooth transmission ring 51. A linkage transmission block 53 is arranged at the front end of the outer tooth transmission ring 51. A threaded through hole is formed at the central part of the linkage transmission block 53, and a transmission adjusting screw 54 is arranged in the threaded through hole. One end of the transmission adjusting screw 54 extends out of the box and is connected with a torque monitoring sensor 55. A torque servo motor 56 is arranged at the upper end of the torque monitoring sensor 55. A limiting guide sliding block 57 is slidably connected to the sliding slot at the rear end of the linkage transmission block 53. An inclined rack 58 is arranged at the front end of the limiting guide sliding block 57. An inner inclined rack 511 (cooperating with the inclined rack 58) is arranged at the inner side of the limiting guide sliding block 57. An arc-shaped material blocking sealing baffle 513 is arranged on a transmission support plate 512 extending through the discharging through slot at the front end of the limiting guide sliding block 57. High-elastic sealing rubber pads 514 are arranged on both sides of the arc-shaped material blocking sealing baffle 513.

[0043] When working, the torque servo motor 56 drives the transmission adjusting screw 54 to rotate, and drives the linkage transmission block 53 at the lower end to move. Through the meshing of the outer tooth transmission ring 51 and the transmission teeth 59, the other linkage transmission blocks 53 are synchronously moved. The inclined rack 58 of the linkage transmission block 53 cooperates with the inclined rack 511 of the limiting guide sliding block 510, drives the arc-shaped material blocking sealing baffle 513 to move, realizes the sealing of the discharging through hole, and the high-elastic sealing rubber pads 514 enhance the sealing performance. The torque monitoring sensor 55 monitors the torque to ensure that the sealing force is appropriate, effectively preventing the overflow and leakage of the rubber compound.

[0044] The effects achieved by the whole mechanism are as follows:

[0045] After the device is started, the rubber compound to be processed is introduced into the premixing and stirring treatment box 2 through the intelligent proportioning feeding control device, the feeding guide groove 21 at the upper end of the premixing and stirring treatment box 2 enters the box, and the uniform mixing of the material and the cleaning of the box wall are completed by the self-adaptive cleaning stirring assembly 7. The stirring motor 78 in the gear protection box 22 is started, the output end drives and rotates the driving gear 73 connected thereto, through the cooperation of the rotating gear 79 at the outer end of the two driving gears 73 and the transmission chain 710, the two driving gears 73 realize synchronous rotation, the driving gear 73 is meshed with the linkage gear 72 around it, and the linkage gear 72 is meshed with the inner side of the inner tooth transmission ring 71, forming a transmission structure, driving the synchronous rotation of the stirring rod 75 at the axis of the driving gear 73 and the stirring branch rod 74 at the axis of the linkage gear 72, and the high-speed rotation of the stirring blades 76 on the surfaces of the stirring rod 75 and the stirring branch rod 74 realizes multi-dimensional shearing and turning of the rubber compound in the premixing and stirring treatment box 2 to achieve uniform mixing, and the warehouse wall cleaning blade 77 on the surface of the stirring branch rod 74 close to the inner wall of the box rotates with the rod to scrape off the residual rubber compound on the inner wall of the premixing and stirring treatment box 2 in real time, avoiding scaling or uneven mixing. The premixed rubber compound enters the material control execution mechanism 3 through the passage at the lower end of the premixing and stirring treatment box 2, the electric control driving pump 34 receives the instructions of the PLC main control panel 4, drives the telescopic driving rod 33 to stretch and retract, drives the control amount resistance adjusting plate 32 to slide in the limiting groove at the upper end of the transition box 31, adjusts the amount of rubber compound entering the rubber compound extruder body 1 per unit time by changing the gap between the control amount resistance adjusting plate 32 and the inner wall of the transition box 31, and at the same time, the flow guiding motor 37 is started to drive the rotary adjusting control rod 35 to rotate, and the flow guiding and homogenizing blades 36 on the surface thereof rotate to perform secondary stirring on the rubber compound passing through the transition box 31, so as to ensure that the rubber compound entering the rubber compound extruder body 1 is uniform in texture. In the process of the rubber compound passing through the material control execution mechanism 3 and entering the spiral extrusion conveying mechanism 8, the intelligent temperature control regulator 6 intervenes throughout the process, controls the electromagnetic induction heating pipe 62 in the heat conduction energy storage warehouse 61 to start according to the preset temperature parameters of the rubber compound type, the heat conduction energy storage warehouse 61 transmits heat to the inside of the conveying cylinder 81, and at the same time, indirectly heats the transition box 31 of the material control execution mechanism 3, the power of the electromagnetic induction heating pipe 62 is dynamically adjusted according to the real-time temperature feedback, combined with the heat storage characteristics of the heat conduction energy storage warehouse 61, to ensure that the temperature of the rubber compound is stable during the controlled amount conveying and spiral extrusion process, and to ensure its fluidity and viscosity.The material enters the screw extrusion conveying mechanism 8 in the body 1 of the material extruder. The conveying motor 83 in the power drive box 12 is started, driving the conveying auger 82 to rotate at high speed in the conveying cylinder 81. The inner diameter of the front end of the conveying cylinder 81 gradually decreases along the axis. The material moves to the extrusion terminal box 11 under the pushing of the conveying auger 82. In the process, the material is subjected to gradually increasing extrusion pressure due to the narrowing of the channel, and finally forms a high-pressure material flow. The flow monitoring sensor 84 at the upper end of the conveying motor 83 monitors the instantaneous flow of the material in real time and transmits the data to the PLC main control panel 4 in real time. If the flow deviates from the preset value, the PLC main control panel 4 immediately instructs the material control execution mechanism 3 or the conveying motor 83 to correct, forming a closed-loop control. When the material is output through the discharge hole of the extrusion terminal box 11, the anti-overflow and anti-leakage sealing mechanism 5 avoids material overflow and leakage through dynamic sealing control. The torque servo motor 56 receives the instruction of the PLC main control panel 4, drives the transmission adjustment screw 54 to rotate, drives the lower end linkage transmission block 53 to slide along the sliding groove of the fixed mounting block 52, the transmission teeth 59 on the inner side of the lower end linkage transmission block 53 mesh with the outer tooth transmission ring 51, drive the outer tooth transmission ring 51 to rotate, and then make other linkage transmission blocks 53 slide synchronously. The inclined rack 58 at the front end of the linkage transmission block 53 meshes with the inclined rack one 511 of the guide positioning sliding block 510, drives the guide positioning sliding block 510 to move, and finally drives the arc-shaped material blocking sealing baffle 513 to gather or move away from the center of the discharge hole. When sealing is needed, the arc-shaped material blocking sealing baffle 513 gathers, and the high-elastic sealing rubber pad 514 on its surface tightly fits the inner wall of the discharge hole to form a ring-shaped seal. The torque monitoring sensor 55 monitors the torque of the transmission adjustment screw 54 in real time to ensure that the sealing force is moderate. When discharging is needed, the baffle moves reversely to open the channel, ensuring the smooth output of high-pressure material. The whole process realizes the quick switching of sealing state and discharging state, and the sealing force can be adjusted, effectively meeting the sealing needs of materials with different viscosities and pressures.
